That's coax, taking it it's you're TV cable, should go to your modem, not to you PC. If it's an actual coax network cable it just puzzles me why you still have that. The picture isn't exactly clear on that. Either way, coax+PC usually is a nono. Unless it's for TV tuners, which is a completely different story.

Assuming you're talking about some sort of cable internet service, cable uses different protocols than your standard ethernet cable and can not simply be "adapted" to ethernet. This is why you need a modem. The modem "translates" the cable network protocol to the ethernet protocol.

If you're talking about cable TV, you will need a TV Tuner, which your motherboard does not have. You can buy these online or at a retail store.

What would probably help is if you could take a picture of the back of your old computer for us. Tell us what this cable is for and how it worked in the past (assuming this is from an older computer).

or install new internet connection (cable and receiver). Any suggestions?
I want to use radio internet connection. Is this possible to connect it to Realtek 8111B (10/100/1000 Mbit)?

Apart from the connector being different here the signal on the cable is most likely different. I highly doubt you somehow have been using such an ancient standard. I'm guessing you're using some docsis thing.

The device in this picture will not work. The type of coaxial connection looks like is meant for a 10base-T or similar BNC connection. The wire you are holding up in your first post is not a BNC cable.

If you have subscribed to a cable internet service, you need a compatible cable modem. There is no way around this. You will need to call your Internet Service Provider and ask them for a modem.

Please explain what you are trying to do. If this cable was previously attached to a different computer, could you tell us what motherboard and/or provide a picture of where it connected?

I still think we really, really need to know what that cable is attached to.

Look at his fingers, seems too thick for wifi. Antenna cables mostly look the same, just different sizes. I'm pretty sure it's just some PCI cable modem or something. If not, he should just call his ISP and ask them what to get instead of having us puzzle.

I took off from work....closed the PC repair for good Yesterday thank god.

More hours no extra pay well a little. WAY MORE TIME. Now I'm ready to do what I want to do....well here soon at least still working there(total other business in imaging) BUT looks like software sells and support is where the boss man wants to go.....if he would of just hired or let me do sells we would not be in the spot we are in. IDK it's always money. I'm going to the school to do sells over our soft(Have too their rules)then we get hit with some 15thouansd dollar bill. Happens every time.....I would not of cared if we just got a certified guy to do sells. At least there would be more to do right now it's all upkeep no new.
